Exactly, the Nissan 6 cylinder engines are among the best and very smooth. I had two Teanas with the 2.3 and 2.5 litre 6 cylinder engines respectively. I also think the 2016 and newer models are 4 cylinders only. A pity since Nissan was the only brand in this segment still offering a very smooth and quiet 6 cylinder motor. The 2.5l Teana model came with CVT which took a bit of getting used to but eventually I found to be working well in combination with this engine.
